An analysis of nearly 500,000 running times estimates the effect of shoes on race performance.

I love the interactive charts and stats in this article. The change in performance graph is the most telling: 85% of runners who switched to the Vaporfly go faster.

Also, I am really surprised how well the Adizero shoes performed – I haven’t heard as much noise about that shoe. I like the Adizero’s looks a lot. There is an Undefeated collab version that I’ve been eyeing.

This is so much what I’m into at the moment: sneakers, interactive stats, and great writing.
